**[Calibration Board Type]**
*   **Black and White Grid Calibration Board:** Detects the intersections (corners) of black and white squares. The pattern must be complete and clear; occlusion will cause recognition failure.
*   **Symmetric Circular Grid (No Offset):** Detects the centers of circles arranged in a regular pattern (e.g., a 7×7 array).
*   **Asymmetric Circular Grid (Odd):** Detects circle centers where the number of rows and columns differs (e.g., 6 rows and 7 columns).

**[Calibration Board Rows]**: Defines the grid arrangement of valid feature points inside the calibration board.
*   For example, in an 8x8 chessboard pattern, the internal corners actually form a 7x7 grid.
*   For a 7x9 circular grid, it indicates there are 7 rows and 9 columns of circle centers.

**[Grid Width]**: The actual physical distance between the centers of adjacent feature points on the calibration board. This value must be entered accurately.

**[Calibration Group]**: Select the corresponding coordinate system group. The calibration data will be recorded in the calibration file under this group.
*   *Note:* The coordinate system group must be configured in the "Coordinate System Calibration" section of Global Data Management.

**[Calibration File]**: Select the calibration file under the chosen coordinate system group. The calibration data will be saved in this file.
*   *Setup Instructions:* The calibration file must be configured in the "Coordinate System Calibration" section of Global Data Management. First, add a coordinate system group. Then, drag both the camera and robot icons into the window under the corresponding group. Connect the two icons with a line to generate the calibration file.
